In my last post, I brought up the idea of integrating seats into carbon bicycle frames (probably not the most practical idea, but something I just wanted to throw out there). I failed to mention the current crop of road bikes on the market that use standard saddles but have seatposts integrated into the frame. If you leave the realm of production bikes, you will find many bikes on the pro circuit, especially time trial machines, with seatposts integrated into the frame. I won’t go into to those, but I want to mention the bikes that you can actually buy with the seatpost built into the frame. Michael prompted this post when he left a comment about the Giant TCR Advanced, the production version of the bike that Jan Ullrich and the T-Mobile team ride. The T-Mobile TCR is a great bike, but it is not the only one on the market with an integrated seatpost. Ridley’s Noah is another really great looking bike that does away with a traditional seatpost. The BH Global Concept framesets that are used by the Liberty Seguros Team have a similar post design. I believe that BMC sells a version of the time machine, like the team Phonak time trial bike, as a frameset with an integrated seatpost. And, of course, I can’t forget Cervelo, who started integrating seatposts into P2 frames in the nineties (or was that a fairing with a seatpost inside?). Today, the P2 uses a separate seatpost part that creates an integrated aerodynamic form, but can be disassembled and, I presume, replaced if necessary. Not exactly an integrated seatpost, but close. That is all I can think of right now, but there are probably several more. If anyone knows of any more production frames like these that I am missing, let me know with a comment.
